Key Takeaways
- A Work Permit, S Pass, and Employment Pass (EP) are different Singapore work passes designed for different groups of foreign workers.
- Work Permits generally cover skilled and semi-skilled migrant workers in approved sectors, while S Passes are for skilled workers and EPs are for professionals, managers, executives, and specialised roles.
- Medical requirements differ by pass type. A medical check up for work permit holders is a defined part of the Work Permit process, while EP and S Pass medical examinations depend on the requirements stated in the In-Principle Approval (IPA).
- Understanding the correct pass helps employers and workers prepare the appropriate application, medical documents, insurance, and other requirements.
Are Work Permits the Same as E/S Pass?
A Work Permit is not the same as an S Pass or Employment Pass. They are separate Singapore work passes with different target workers, eligibility criteria, employment conditions, quota rules, and medical requirements. A medical checkup for work permit holders may involve specific health assessments depending on the applicable requirements.
The Ministry of Manpower (MOM) identifies the Work Permit as a pass for skilled and semi-skilled migrant workers in sectors such as construction, manufacturing, marine shipyard, process, and services. The S Pass is intended for skilled workers, while the Employment Pass is for foreign professionals, managers, executives, and specialised professionals. Medical checkup for work permit applicants should be considered in the context of the relevant pass requirements.
What Is a Work Permit?
A Work Permit allows eligible foreign workers from approved source countries or regions to work in sectors such as construction, manufacturing, marine shipyard, process, and services. MOM states that there is no minimum qualifying salary, although employers must meet quota and levy requirements. A Work Permit can be valid for up to two years, depending on factors such as passport validity and other permit conditions.
Employers must also provide required medical insurance and, where applicable, a Primary Care Plan. Medical check up for work permit holders is part of the compliance process.
Employers generally must arrange a medical screening for work permit holders within two weeks of arrival with a Singapore-registered doctor or appropriate appointed provider. The examination checks fitness for work and screens for infectious diseases.
What Is an S Pass?
The S Pass is intended for skilled foreign employees, including eligible associate professionals and technicians. Unlike a Work Permit, it has a qualifying salary requirement that varies according to age and sector.
A medical examination is not automatically identical to the Work Permit process. The S Pass IPA indicates whether an examination is required after arrival, so employers should follow those instructions rather than assume the same tests apply to Work Permit applicants.
What Is an Employment Pass?
The Employment Pass is designed for foreign professionals, managers, executives, and eligible specialised professionals. Applicants must meet prevailing criteria, including salary requirements and, where applicable, the Complementarity Assessment Framework (COMPASS).
Its medical process also differs from the Work Permit. The IPA states whether the candidate needs a medical examination after arrival. If required, the employer or candidate should follow the IPA instructions and submit the necessary documents.
Therefore, Singapore’s medical check up for work permit holders should not be treated as the standard procedure for every foreign employee. The pass type determines the applicable rules.
Work Permit vs S Pass vs Employment Pass
| Feature | Work Permit | S Pass | Employment Pass |
| Main worker group | Skilled and semi-skilled migrant workers | Skilled workers | Professionals, managers, executives and specialists |
| Typical sectors or roles | Approved sectors such as construction, manufacturing and services | Skilled roles across eligible sectors | Professional and specialised roles |
| Salary requirement | No minimum qualifying salary | Qualifying salary applies | Qualifying salary and other criteria apply |
| Employer quota | Yes | Yes | No general quota |
| Medical examination | Required for Work Permit issuance | As stated in IPA | As stated in IPA |
| Family passes | Not available to Work Permit holders | May be available if requirements are met | May be available if requirements are met |
A medical check up for work permit applicants may involve specific forms, tests, and submission procedures that are not automatically applicable to S Pass or EP candidates.
What Happens During a Work Permit Medical Examination?
The purpose of the Work Permit medical examination is not simply to provide a general health screening. MOM states that it checks whether the worker is fit to work and screens for tuberculosis, HIV, syphilis, and malaria. Additional tests may be arranged when there are specific health concerns.
A medical check up for work permit issuance must be completed and certified appropriately before the permit can be issued. From May 2026, medical service providers can submit relevant results directly through MOM’s Medical Examination Portal, reducing the need for employers to upload hard-copy medical reports or chest X-rays during the Work Permit issuance process.
Why Medical Requirements Should Not Be Confused
Although all passes allow eligible foreigners to work in Singapore, their medical requirements are not interchangeable. A Work Permit has a defined post-arrival examination process, while S Pass and EP candidates should follow the medical requirements in their IPA.
This matters for employers hiring different categories of foreign workers. Booking the wrong examination or using the wrong form could delay pass issuance. Before arranging a health check up for work permit applicants, confirm the pass type, IPA instructions, timing, and approved provider.
Workers should bring requested documents and provide accurate medical information. A work permit medical check up should be arranged using the correct MOM process. Abnormal findings may require additional assessment before the pass process is completed.
Choosing the Correct Pass
The pass depends on the worker’s role, qualifications, salary, nationality or source-country eligibility where applicable, and the employer’s sector and quota. Work Permits generally cover approved sectors and skilled or semi-skilled migrant workers. S Passes are for eligible skilled workers, while Employment Passes are for higher-skilled professional, managerial, executive, and specialised positions.
Employers should not choose a pass based only on the job or worker’s preference. MOM’s eligibility rules determine which pass is appropriate and can change over time.
For employers arranging a medical check up for work permit applicants, verifying MOM requirements before the appointment helps ensure the correct examination is completed on time.
Conclusion
Work Permits are not the same as S Passes or Employment Passes. They are separate Singapore work passes with different target workers, eligibility criteria, employment conditions, quota rules, and medical requirements. Work Permit holders generally undergo a required medical examination as part of permit issuance, while S Pass and EP candidates follow the medical instructions stated in their IPA.
Understanding these differences can make the work pass process smoother and reduce avoidable delays. Employers should confirm the applicable pass, review the latest MOM requirements, and arrange a medical check up for work permit holders with an appropriate Singapore-registered medical provider when required.
For S Pass and EP candidates, the IPA should be used to determine whether a medical examination is needed and what documentation must be submitted. A medical check up for work permit holders should follow MOM instructions carefully.
